Meant to be Seen

Hello Everyone,
This are the notes from the original software engineer:

"The relevant source files are in the EngineCore and EngineApp folder. It will need someone with VC++ experience to make sense of the files. The EngineApp is the project runs the main process. There is another project in the Solution but it is not being used anymore."

I hope this help anyone.

Regards

Hannibal, your design looks outstanding. Not sure if many (or really any) people here remember the Cinerama theaters that used the ultra-wide format, but this very much reminds me of it.

It'd certainly be sweet to watch 3D content in full HD with this headset. Looking forward to more updates as you progress.

Hello Everyone,

It's been a while since I have posted anything here. I wanted to let you all know, that if anyone feel they want to take a knack at making some adjustments to the original printing HMD file, I may provide it such as OBJ, or other formats. The only condition is that all changes must be shared back to the community.

Cheers all, and keep on DIYing!

Hello Spook50,

Thanks for the compliment. But I am not actually familiar with it. I will check it out!

Has anyone looked at 3m press-on aspheric fresnel lenses? They look to be available in a wide selection of diopters.

the 3m press-on fresnel prisms might be handy for adjusting the stereo overlap too.

Cheers

Thanks for the info, I have not tried them. It comes down to the size.

Hello Everyone,

If anyone ever downloaded the material and wish to comment, it would be nice if can update here on the thread. I hope many of you are having fun creating your own creations!

Hi Guys!
I am really exited about this project and I want to create my own glasses...
I saw that the InfinityEye (V1) used 4 Lenses from Optolife. Does this Glasses also uses 4 Lenses? Or are 2 OK for 180° FoV?

Hello PonjtFX.

In order to gain massive FOV with current available lenses, 4 lenses is the way. If you can get Lenses with 40mm or 30mm magnification that would be ideal since you may only need one per eye. However, those would need to be custom ordered. But that is not the only problem when getting larger magnification lenses, there are other factors as well. If you want to keep it on the cheap you should get the 120mm or 100mm.

Have fun!

Quite a while back, I had suggested the idea of using the flexible OLED display (or alternatively a small projector) to put an image on something that would look like a face splash guard type of face protector0
They are fairly cheap, and here is one costing only $17. http://www.grainger.com/product/TASCO-F ... 2?$smthumb$ .

Since the display itself would be lighter than a LCD display, it would allow placement of the screen a little further away than what the Rift does. Then you should be able to just use strong reading glasses for the optics. Additionally, people who wear glasses are already used to the idea that objects outside of the frames of the glasses are out of focus.

Stereo can be achieved by using LCD shutter glasses, so I wonder if those are available in a version with a wide view, or perhaps even if the shutters themselves don't cover as much of the view area as we would prefer, the area to the sides of the shutters can just be regular sunglass type of plastic, to keep the brightness of the image the same as when you look through the shutters.

Regarding your existing design. The flexible OLEDs have been demonstrated for a few years now, but they are still fairly rare in the consumer market. Perhaps the technology is proving harder than the manufacturers are admitting publicly. So, your existing design may still be valid for a while, even if the flexible OLED displays were to eventually become a better choice.

I should also note that few people have both artistic and engineering abilities. You seem to have both in abundance.

Hi giuys what kind of Fresnel lens should i use and what size /shape should i cut them?

Thanks in advance

I will give you more in this answer than what you asked.

At this time around, I suggest to try use smaller displays than the 7nch I used. Go to the RiFTUP thread and try get some 1080p's with controller boards at 5.9 inches, from Rozno

You can try several lenses and play with them. Stacking 120mm on each eye works but... the image does suffer. Ideally if you can use singled 40mm of augmentation for each eyes would be great, except that the circumference of the pupillary exit is too small as well the actual lense. For the perfect lense, it would need to be made custom.

Try stacking a few such (2 on each eye):

1. 120mm
2. 100mm
3. 90mm (As you start increasing augmentation, the size of the glass/plastic will be smaller) This might determine the size of the casing of your HMD, thus affecting the WFOV.

In order to achieve 180 FOV, the angled lens have to be at the same level of where the eye reside of the users head. If you put the lenses flat in front of the face, it can never create full 180FOV

Good luck

Thanks Joe!

I will focus at the moment on content creation for VR. Hardware is a bit tricky at the moment since everyday there is a new player in town. Perhaps after VR is released and the weaker links fall, I may study the situation and the current state of affairs.

My current target is how to offer 360 degree environment narrative content. I will collaborate with a university to make some short test. If the results are good I will share it. I am strictly focusing on the Rift at the moment though.

If you are working on content, I will mention an area that seems to be non-existent in the low-cost VR world. CAD design is the world I work in, but I cannot find any solution to view a model in steroscopic mode. AutoDesk, at one point, added stereo support for their free viewer, but then they later removed that feature. In the past I have seen systems that required you to export a model from the CAD program to VRML format. But, that export format seems to have fallen out of favor, and I currently don't know of a way to create that format.

For a very wide format VR headset to use with CAD, the type of application that most would benefit would obviously be architectural. Perhaps if you could link Sketch Up to the Rift, that would be one particular popular area where their may not be competition, like there is in the game world. The link might be directly to the program (I don't know if that is really viable), or by your program directly accessing the Sketch-up file as a simple viewer.

CAD "can" be a very large market for VR, and i have seen random attempts.

Have you checked the "Stem Sixsense" lately? CAD is reliant of interactions, so good hap-tics are needed. The Stem is trying to solve this from some recent videos I have seen.

Autodesk is not the quickest to adopt new technology.

Mudbox for example just recently allow to interact with touch controls. However, I think its limited to the Wacom Cintiq line of products and not all Wacom enabled touched products. For sure they are not compatible with N-trig digitizers which a large base of touch computers include.

If VR does expand and the market grow, you will see Autodesk making beneficial changes and inclusion of VR compatibility. If not them, competitors may jump in, this will put some pressure to Autodesk.

When I look at the Stem by Sixsense, it seems to be mostly for tracking. There was another system I looked at, the Falcon haptic system with force feed-back by Novint.
http://www.novint.com/index.php/products/novintfalcon. At only $250 it seemed to be quite affordable. Their initial demo of the prototypes showed a person using it to drag a virtual probe over virtual surfaces such as wood and ceramic, and they could tell the difference in texture. But neither they, nor anyone else have a driver for it to work with a CAD system. They only market it for games.

By they way, Novit also has a haptic arm that looks quite intriguing, but it has been "coming soon" for a very long time, and seems to have stalled.

Hi,
First of all, sorry for my poor English

I'm very impressed with your project.
It's awesome!!!
I think it beats oculus drift in every way, at least at the moment.

I'm considering make one myself.
But i'm newbie... (only a few tests with cardboard for cell phone)
So i wonder if you can answer some basic doubts i'm having.
My build would try to be at the most "low cost" way

What do you think of using of this stuff?

-2 x 7"lcd 1280x800 like this:

http://www.ebay.com/itm/HDMI-VGA-2AV-Lc ... 2a2d5f7806

-4 x Fresnel lens like this:

http://optolife.com/diy_projector_lens/FRL021.html

-Case based in your great design (Portal Dual 180 Wide FOV HMD Case) but probably handmade

-Head tracking: Arduino based (i made some success experiments that way)

Regards!

Hello Nakon,

I suppose you could try those displays. The lenses are fine also. The best way is for you to check the refresh rate of those lcd's. There are lcd's that have 13-16 milisec refresh rate, i would suggest those.

Hi all ,

here it is something about flexible OLEDS - production plan ....very interesting

http://news.oled-display.net/flexible-curved-oled/



I am too building my HMD (I have DK1 with RiftUp and DK2 too but i want to build HMD for old XP Direct X7 Condor soaring simulator (3D old NVidia drivers, dual panel 3D = two VGA outputs (is working fine!). main problem is that 7" panels are too big (IPD is wrong with Nvidia 3D drivers) I am waiting for 5,6" panels (but 30 ms latency)...Have too two Full HD panels 5,6 panels with boards (as RiftUp) but they have only HDMi input, cant use VGA....

"Wide FOV visual displays have long been associated with increased
susceptibility to SS (Hein, 1993; Kennedy & Fowlkes, 1992; Kolasinski, 1995;
McCauley, 1984; Pausch et al., 1992). This is because with a wider FOV there is a
greater perception of visual flow or vection."

Hello Martin, Thanks for the info!


On a different note,
Does anyone knows what happened to "Geekmaster" I have not seen any post in a while anywhere.

I thing this is the reason why DK1 with original panel 7" was producing more ss as DK 1 with 5,9" Riftup or DK2. But I think that enough FOV is wery important. What about 8,4" 2560*1600 panel of galaxy S tablet - ideal upgrade for DK1.

https://www.youtube.com/watch?v=x1F2YZN5vDY#t=282 Money shot is at time 4:42 Here is David Smith with Lockheed Martin, showing new 150 and 180 FOV display. I got to put my head in this thing.

Are this high FOV hmd stereoscopic? How big is the overlap?

That is very nice! Curved display, I wander the type of optics they use. 100 grams must feel incredible comfortable. This type of videos make me reconsider going back to continue development of the Portal Dual.
Those units must still be ridiculously expensive though.

Very cool link Martin!

hi Hannibalj2

thanks you so much for your jobs! this is amazing! I want to make my hmd with yours plans and solutions . But i 've got a question: can we use tridef, vorpx, or vireio with this hmd???

You could try them but the one main problem is that they many not have enough controls for convergence for dual display. Also the warping shaders may not be great ( The old version of Vireioh).
The lenses will be angled so there will be a mild distortion and I'm not sure those software account for that.

That said, give it a try. If you are a coder, you can tinker with the engine I have included and extrapolate the convergence controls and build a driver injector. Or maybe somebody could add it into Vireioh. I have not tried vireoh for some time, so Im not sure how many more options they have added, especially for a dual display HMD.

Thanks for your quick answer

unfortunately i'm not a coder, and i think it will be too long to learn how to do it. But it's not a problem, i will make this hmd, and i will find solution.... I hope

When my project will forward, i'll post photos and products links. I wait few days before order screens + board, because at CES 2015, OSVR project speak about 5.5 FHD screen. Maybe it 's a MIPI screen, so a HDMI to MIPI/DSI board shall exist, and as they speak about 199$ for complet hdm, the board may be sold at a very good price
So i can dream about a dual panel HMD with 2560/1440 per eyes

Thanks again for you job

I thing VRunion stole your concept. Check out "Claire" at vrunion.com

It makes me sad that you had this idea so long ago and I did not know about it.

[quote="Hannibalj2"]You could try them but the one main problem is that they many not have enough controls for convergence for dual display.

Hi I am building something similar as your HMD, tested some Fresnels but the result was not so good (picture is not sharp enough). Have you tested temporal (out) decentration of lenses to make 100% overlap of pictures? I want to make big +20 (+25 D) lenses (f 50 or 40 mm) and then decentrate them. But near all are aspheric and this would be not working I think.
Thx

Peter

Do you know some optical designer? Thx

There seems to be a problem with the website that is hosting all download files for the Portal Dual. If the problem remain, I will host it somewhere else.


Cheers!

I'd be quite keen to be able to download these files from somewhere. It seems to me that the simplest way to get them back online would be to create a simple static page hosted by github under their "github.io" static file hosting service (free). If you're not keen on web stuff, feel free to shoot me an e-mail (at my username, at gmail) with the files you'd like hosted, and a description of how you'd like it to be presented, and I'll happily set up a github repo for you to fork.

Hi, sorry for my english. Your desing is amazin. I do the other proyect, with 2 LCD 7" , foam and fresnel lens. I want use for fpv with my Dron. But i think that this proyect with 2 LCD is’n use like sidebyside, duplicated the same image in the LCDs. The image look double. Thanks

Can I ask you a question?
Which side of Fresnel lens facing the lcd , grooved or Flat side?
thenks

Ylvov wrote:Can I ask you a question?

Grooved side should face LCD, smooth side should face they eye.

Do you have a parts list? I'd like to know where to buy the displays and lenses.

I want to use the Sony 4k phone screen. What is needed to make this work?
http://www.etradesupply.com/sony-xperia ... black.html

It is not so simple , the phone screens need HDMI to MIPI bridge, 4k is not available i think...input is not HDMI direct...all is somplicated too only full HD. But you can buy 2560x1440 LCD screen with HDMI input board from topfoison.

Im considering buying one of these screens (topfusion) and dropping it into a old diy 5.5 inch HMD i made a couple of years back - but now that ive seen this project im considering buying two screens

What are the ideal lens to use for the casing in this thread? http://www.thingiverse.com/thing:287148 Is that casing complete? A single STL?

Maybe I should revisit this project?

You should, and upload it to Github! Been following this thread for a long time.
